iOS itunesconnect sandbox test account (Invalid Year)

Question

This is so weird! last week I created a test user account and it was just fine but today, it is asking me for adding birth year! as you see in the below screenshot. there's no year field to fill in and it is asking for it?! Apple, are you serious? if I'm doing something wrong, please tell me...

UPDATE: it seems like it was a bug on apple's page. it worked just now. I lost two days though!

Answer 1

This was a temporary bug in itunesconnect between 27th and 30th of August.

Same problem also mentioned in
